Document Type and Number:
Japanese Patent JP2023115228
Kind Code:
A
Abstract:
To provide a refrigeration cycle device comprising a first refrigerant circuit and a second refrigerant circuit, and enabling efficient operation.SOLUTION: A refrigeration cycle device comprises a first refrigerant circuit (10) using a first refrigerant of 1.2 MPa or less at 30°C, and a second refrigerant circuit (20) using a second refrigerant of 1.5 MPa or more at 30°C. The refrigeration cycle device can switch between a binary cycle operation in which the first refrigerant circuit (10) and the second refrigerant circuit (20) are simultaneously operated to perform heat exchange between the first refrigerant and the second refrigerant, and a unit cycle operation in which the first refrigerant circuit (10) is operated without operating the second refrigerant circuit (20), to perform cooling operation or heating operation.SELECTED DRAWING: Figure 3
